CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 773,667, dated November1, 1904.

7 Application filed January 30, 1903. Serial No. 14=l,151. (No model.)

To all whom it may concern.-

Be it known that 1; JAMES J. MoCARTHY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, l1aveinvented certain new and useful Improvements in Car-Roofs, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to roofs, and hasparticularly to do with metallicroofs for cars and other structures. It has for its object to providecertain improvements in roofs adapted for use in exposed situations,such as that shown in my Patent No. 718,145, dated January 13, 1903.

The improvements which form the subjectmatter of this application relateparticularly to devices for securing the upper and lower ends of theroofing-plates. In the construction shown in my Patent No. 718,145,above referred to, the lower ends of the roofingplates project beyondthe side edges of the roof and are bent over such side'edges, projectinginto recesses between the faciaboards and the sides of the car. The endsof the roofing-plates are not, however, otherwise secured.

One feature of my present invention consists in providing means by whichthe lower ends of the roofing-piates are secured in place withoutinterfering with the adaptability of the plates to accommodatethemselves to wrenching strains of the car.

A further feature consists in providing for securing the upper ends ofthe roofing-plates at the ridge-pole.

In the accompanying drawings, Figure 1 is a cross-section of the roof ofa car near one end, illustrating my improvements. Fig. 2 is a similarview taken nearer the middle of the car. Fig. 3 is an enlarged detailillustrating the arrangement of the upper ends of the roofing-plates andthe ridge-pole. Fig.

4 is an enlarged view of the lower end of one of the roofing-plates andthe supporting devices therefor, taken near one end of the car. Fig. 5is a similar view taken near the middle of the car. Fig. 6 is a partialside View showing the lower ends of the roofing-plates and adjacentparts, and Fig. 7 is an enlarged sectional view of the lower end of oneof the roofing-plates.

Referring to the drawings, 8 indicates the wooden roof of a car, and 9the ridge-pole.

10 indicates the roofing plates, adjacent plates being united,preferably, in the manner shown in my patent above referred to. As bestshown in Fig. 3, the ridge-pole 9 is provided along its under side edgeswith grooves 11, adapted to receive loosely the upturned ends 12 of theroofing-plates, thus preventing water from passing up over beyond theupper ends of the plates and leaving the plates free to accommodatethemselves to wrenching strains. The lower ends of the plates extendbeyond the side edges of the roof 8, as shown in Figs. 1 and 5, and arebent downward and inward in the manner described in my patent abovereferred to, lying between the facia-boards 13 and the siding 14E of thecar. (Best shown in Figs. 1 and 5.) The upper inner edges of thefacia-boards 13 are beveled in the manner described in my former patentreferred to.

Near their lower edges the roofing-plates 1O are provided withperforations 15, adapted to receive washers 16, which are somewhat lessin diameter than said perforations, so that they do not interfere withthe requisite adjustment of the roofing-plates. This is best shown inFig. 7. The washers 16 are somewhat thicker than the ro0fing-plates andfit closely between the inner surfaces of the faciaboards, as shown inFig. 1. Each of said washers is provided with a perforation 17 for thepassage of a nail 18, by which the washer is secured in place, therebysecuring the lower edges of the roofing-plates in place.

19 indicates the rails upon which the cardoors slide, and 20 indicatesthe covering, which extends over the car-doors, as shown in Fig. 5. Oversuch covering 20 the lower edges of the roofing-plates are bentdownward, as shown at 21 in Fig. 5, extending under the facia-boards 13,thereby directing any moisture outward and preventing it from passingdown under the covering 20.

22 indicates the nails or bolts by which the facia-boards are secured inplace.

I thus provide for supporting the roofingplates at the top as well as atthe bottom in car-door covering and the side of the car is such mannerthat while they wholly prevent leakage of moisture into the car they arenevertheless free to accommodate themselves to wrenching strains of thecar-body, which would otherwise weaken and ultimately destroy them.

That which I claim as my invention, and desire to secure by LettersPatent, is-

1. In a car-roof,the combination of support ing devices, roofing-platescarried thereby, said roofing plates having projecting ends, the lowerend portions of said roofing-plates lying adjacent to the sides of thecar, and washers secured to the car and lying loosely in perforations inthe lower end portions of the roofing-plates, substantially asdescribed.

2. In acarrooi,the combination of supportingdevices,roofing-platescarried thereby,said roofing-plates having projecting ends, faciaboardssecured to the sides of the car, the upper ends of said facia-boardsbeing slightly removed from the sides of the car, thereby formingrecesses adapted to receive the ends of the roofing-plates, and washersbetween said facia-boards and the sides of the car, said washers lyingloosely in perforations in the lower end portions of the roofing-plates.

3. In a car-roof, the combination of supporting devices,roofing-platescarried thereby,said roofing-plates having projecting ends, faciaboardssecured to the sides of the car, the upper ends of said facia-boardsbeing slightly removed from the sides of the ear,thereby formingrecesses adapted to receive the ends of the roofing-plates, washersbetween said faciaboards and the sides of the car, said washers lyingloosely in perforations in the lower end portions of the roofing-plates,and means securing said washers to the sides of the car, substantiallyas described.

I. In acar-roof,the combination of supporting devices, roofing-plat escarried thereby, said roofing-plates having projecting ends, faciaboardssecured to the sides of the car, and a covering secured to the side ofthe car and extending over the car-door, the lower end portions of saidroofing-plates extending between said facia-boards and the sides of thecar and between said facia-boards and said cardoor covering, whereby thejoint between the protected from leakage, substantially as described.

5. In a car-roofithe combination of supportingdevices,roofing-platessupported thereby, the lower end portions of said roofing-plates beingturned down and lying adjacent to the side of the car, and means securedto the car and lying loosely in perforations in the lower end portionsof the roofing-plates for loosely connecting said roofing-plates withthe car, substantially as described.

6. Inacar-roof,thecombinationofsupporting devices, a ridge-pole havinglongitudinal grooves at its sides, roofing-plates carried by saidsupporting devices and having their upper edges fitted in said grooves,the lower end portions of said roofing-plates lying adjacent to thesides of the car, and means loosely con necting the lower end portionsof said roofingplates with the car, substantially as described.

7. In a car-roof,the combination of supporting devices, a ridge-polehaving longitudinal grooves within its under side edges, and roofing-plates carried by said supporting devices and having upturned upperedges loosely fitted in said grooves, the lower ends of saidroofing-plates extending down beyond the edges of said supportingdevices and being loosely secured to the sides of the car, substantiallyas described.

8. In a car-roof, the combination of supporting devices, a ridge-polehaving longitudinal grooves in its under side edges, roofing-platescarried by said supporting devices and having upturned edges fittedloosely in said grooves, and means loosely securing the lower endportions of said roofing-plates to the car, substantially as described.

9. In a car-roof, the combination of supporting devices, a ridge-pole,roofing-plates carried by said supporting devices and having their upperedges loosely connected to said ridge-pole, and means loosely connectingthe lower end portions of said roofing-plates to the car, substantiallyas described.
